Within the medieval and early modern archaeology in my research, I usually focus on the monuments datable to the so-called transitional periods, namely to the end of the Middle Ages and the beginning of the Early Modern epoch, or to the late "Early Modern" time. The appearance of these transitions in the material culture and the architecture is hardly investigated, maybe because it is extremely difficult to trace small nuances of such processes in the huge mass of the material available from this period. Thus the decay of the fortifications the abandonment of the settlements, the replacing of the traditional, pre-Ottoman material culture is of special interest for me.

The textile production and trade was the main driving force of the medieval and early modern economy. The quality and the origin of the fabrics bore exceptional importance on the contemporary markets and very often the town names became synonyms for specific cloth-types (arras, dornet, galler etc.). To protect the "brands" of the production centres a special seal was introduced from the late 13th century: the so-called cloth seal was made of lead and according to the local regulations was pressed on the edge of the rolls and stayed visible until the last ell was sold. These cloth seals are my main research topic within the material culture of the medieval and early modern Kingdom of Hungary. These items are just like written sources: expressing the date and the location of the - vanished long time ago - cloth they were attached to, and also they tell where this textile fabric was finally used.
